Kyiv (Ukraine) (AFP) – US President Joe Biden promises increased arms deliveries for Ukraine during a surprise visit to Kyiv in which he also vowed Washington’s “unflagging commitment” in defending Ukraine’s territorial integrity. “Together we’ve committed nearly 700 tanks and thousands of armoured vehicles, 1,000 artillery systems… and that doesn’t count the other half a billion dollars we’re announcing with you today and tomorrow that’s going to be coming your way,” Biden tells his Ukrainian counterpart Volodymyr Zelensky.
